Nighttime created a sky for Alberto Santos-Dumont to conquer. He envisaged using a floodlight to light his way during his test flights. Cartier casts light on the night sky with the new Santos de Cartier Skeleton Noctambule.

The case, in stainless steel ADLC, measures 39.8mm x 9.08mm and it has double sapphire crystals.

Movement is the Swiss manual-wind Cartier caliber 9612 MC with 20 jewels, 28,800 vph and a power reserve of 3 days. It features skeletonised bridges in the shape of Roman numerals.

The bridges are coated with SuperLuminova pigments which, while invisible during the daytime, reproduce and radiate the stored light once night falls.
